Conditions at Playa Boca Chica in May
May: Maximum Southern Swell, Humid and Wind-Compromised
May is a study in trade-offs. The average swell height jumps to 5ft (1.5m), the average wave period reaches 14.2s, and an enormous 84 percent of the wave energy is coming from SSW. This is as good as it gets for pure south swell direction at Boca Chica. However, the wet season is beginning: rain increases to 1.42mm/day and the ideal wind percentage sinks to just 41 percent. Onshore and cross-onshore winds from the SW and WSW show up more frequently, and humidity starts to build. When a morning offshore window lines up, the 5-6ft (1.5-1.8m) SSW waves can be world-class, but be prepared for plenty of bumpy afternoons. Water temperatures rise to 29.2°C, so boardshorts and a spring suit are all you need.
